measurements, such as indicator diagrams, the stress diagrams
of beam sections, &c. &c.: see pp. 431-436, 623, 679, 846.

P. 444. Rolling Load.

Ex-ample 74. Prove an algebraic formula to shew that with a
continuous load of uniform intensity passing over a beam A B, such as
when a long train passes over a bridge A to B, the maximum shearing
stress to any point K of the beam occurs when the part A K is fully
loaded while the part K B is entirely unloaded ; and that the magni-
tude of the stress is proportional to the square of the distance of K
from the point A. (Hons. Applied Mechanics Exam.)
